Wikipedia EN

"I know that I know nothing" is a saying derived from Plato's account of the Greek philosopher Socrates. It is also called the Socratic paradox. The phrase is not one that Socrates himself is ever recorded as saying.

This saying is also connected or conflated with the answer to a question Socrates (according to Xenophon) or Chaerephon (according to Plato) is said to have posed to the Pythia, the Oracle of Delphi, in which the oracle stated something to the effect of "Socrates is the wisest."
